Answer 1

Answer:

Newton's first law of motion- According to this law, a body at rest or in uniform motion will continue to be in the state of rest or uniform motion unless it is compelled by an external force to change its state of rest or uniform motion.

Examples:

⋅ An athlete runs for a certain distance before taking a long jump.

⋅ A person sitting / standing on a bus fall back when the bus suddenly starts moving forward.

⋅ The carpet is beaten with a stick to remove the dust particles.

The second law of motion: The acceleration produced in the body by the action of a force acting on its directly proportional to the force and inversely proportional to the mass of the body. Mathematically, F=ma, where, F = force, m = mass of the body.

In other words, Newton's second law of motion can be stated as: The rate of change of momentum is equal to the force applied to the body and the change in momentum always takes place in the direction of the force.

Examples:

⋅ A cricket player lowers his hands while catching the ball.

⋅ A person falling on a cemented floor gets injured, but a person falling on a heap of sand does not get injured.

Third law of Motion: According to this law:

"For every action, there are an equal and opposite reaction" (Law of action and reaction) Examples:

⋅ Gun gives a to shoulder of the gunman on firing a bullet from it.

⋅ Boatman pushes the river bank with a bamboo pole to take his boat into the river.
